Internal cellular structure. Illustration of internal cellular structures (organelles), including the cell nucleus (lower right). Nuclear pores are shown on the surface of the cell nucleus. The cell nucleus contains the cellular DNA (deoxyribonucleic acid). At top left is part of a chloroplast, a structure found in plant cells. The disc-shaped structures, called thylakoids, form a stack known as a granum. The grana are the site of photosynthesis in plants, where the green pigment chlorophyll is used to convert light energy into chemical energy.
